Django评论从发布/预览重定向

我正在实施django评论应用。 单击帖子而不是帖子页面时,重定向到当前页面的最佳方法是什么?

我已遵循本指南:http://www.omh.cc/blog/2008/mar/9/free-comments-redirection/

我的表单如下:

{% load comments i18n %}

<form action="{% comment_form_target %}" method="post">{% csrf_token %}
    {% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}
        {% for field in form %}
            {% if field.is_hidden %}
                <div>{{ field }}</div>
            {% else %}
                {% if field.name != "email" and field.name != "url" %}
                    {% if field.errors %}{{ field.errors }}{% endif %}
                        <p
                            {% if field.errors %} class="error"{% endif %}
                            {% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}>
                            {{ field.label_tag }} {{ field }}
                        </p>
                {% endif %}
            {% endif %}
        {% endfor %}
    <p class="submit"><input type="submit" name="post" class="submit-post" value="{% trans "Post" %}" /></p>
</form>

我的views.py看起来像:

def comment_posted( request ):
    if request.GET['c']:
        comment_id, post_id = request.GET['c'].split( ':' )
        post = Image.objects.get( pk=post_id )
        if post:
            return HttpResponseRedirect( post.get_absolute_url() )
    return HttpResponseRedirect( "/" )

我的urls.py看起来像:

urlpatterns = patterns('',
    url(r'^other/', include('other.urls')),
    url(r'^live/', include('live.urls')),
    url(r'^photo/', include('photo.urls')),
    url(r'^comments/posted/$', 'photo.views.comment_posted'),
    url(r'^comments/', include('django.contrib.comments.urls')),
    url(r'^search/', SearchView(template=None, searchqueryset=None, form_class=SearchForm), name='haystack_search'),

我想我已经修改了我的views.py错误,任何想法?

我的应用程序称为照片,我的模型称为图像。

答案 0 :(得分:1)

我不明白为什么你需要你的comment_posted视图。相反,我认为你应该修复你的下一个领域:

{% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}

这里,如果设置了“下一个”上下文变量,则“下一个”隐藏输入仅被输出。你应该瞄准的是:

    如果可能,
  • 接下来会{{next}}
  • 备注评论对象的绝对网址

它可能看起来像:

<input type="hidden" name="next" value="{% if next %}{{ next }}{% else %}{{ form.target_object.get_absolute_url }}{% endif %}" />

这假设您的模型具有正确定义的get_absolute_url方法。

请注意,我通过阅读

来了解form.target_object
  1. 评论模板标签的代码,我注意到将评论表格与目标对象作为第一个参数进行实例化并且

  2. 我注意到的评论表单的代码将传递的目标对象存储在target_object属性中,使其在{{form}}

  3. 的任何地方都可用
